Not that I intend to fill my 'blog with Bertrand Russell quotes, but still:

Some "advanced thinkers" are of the opinion that any one who differs from the conventional opinion must be in the right. This is a delusion; if it were not, truth would be easier to come by than it is...

On one occasion a man came to ask me to recommend some of my books, as he was interested in philosophy. I did so, but he returned next day saying that he had been reading one of them, and had found only one statement he could understand, and that one seemed to him false. I asked him what it was, and he said it was the statement that Julius Caesar is dead. When I asked him why he did not agree, he drew himself up and said: "Because I am Julius Caesar." These examples may suffice to show that you cannot make sure of being right by being eccentric.
